Description

Technical Field

[0001] This invention relates to the field of dust detection technology, specifically to an environmental detection device for dusty environments. Background Technology

[0002] A dust detector, also known as a dust meter or dust tester, is mainly used to detect the concentration of dust in ambient air. Dust detectors are widely used in disease control centers, mines, metallurgy, power plants, chemical manufacturing, health supervision, environmental protection, online environmental monitoring, and more.

[0003] Current dust environment monitoring equipment suffers from low sampling efficiency. Traditional dust collection structures often rely on natural settling or unidirectional suction, resulting in insufficient dust collection, particularly weak capture of suspended dust, leading to poor representativeness of the sampling data. Furthermore, the equipment lacks flexibility, with fixed probe angles and positions that cannot be adjusted based on dust diffusion direction or changes in the work area, easily missing critical pollution points. Maintenance costs are also high, with low integration between dust collection and detection components, requiring disassembly of multiple structures for cleaning and calibration, making operations complex and time-consuming, impacting the equipment's continuous operating efficiency. Therefore, those skilled in the art have provided an environmental monitoring device for dust environments to address the problems mentioned in the background. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an environmental monitoring device for dusty environments. It solves the problems of poor mobility, incomplete sampling, and delayed detection in traditional dust monitoring equipment, enabling real-time monitoring, efficient sampling, and data feedback of dusty environments, and providing reliable technical support for operational safety protection and environmental quality control.

At the same time, the guide groove is equipped with limiting structures at both ends to prevent the box from sliding out of the mounting base. The side outlet is opened on both sides of the outer wall of the bottom collection box and is equipped with valves to control the on and off. When it is necessary to sample and test the collected dust, the valve can be opened to take out part of the dust through the outlet without opening the sealing cover at the top of the box, avoiding a large amount of dust leakage and environmental pollution, while improving the sampling efficiency.

The latch 75 is installed on the outside of the fixing sleeve 73 and uses an easy-to-operate locking structure. The fixing sleeve 73 and connecting rod 74 can be locked together with simple operation. The operation is convenient and the locking force is strong, ensuring that the fixed base 53 does not loosen when the equipment moves or vibrates.

[0042] Working Principle: During operation, the probe position is adjusted via the rotating frame, connecting rods, and top rotating joint. The angle between the guide port and the dust collection plate is adjusted by the drive motor. The drive motor starts, rotating the driven gear via the active gear and rack, causing the top rotating seat to rotate accordingly, aligning the guide port with the dust source. The dust collection plate captures suspended dust through adsorption, while the dust enters the guide port under airflow, passing through transmission pipe one, the top rotating seat, and transmission pipe two into the top transmission seat. A blowing fan starts periodically, blowing air into the transmission seat through the blowing pipe, dislodging the attached dust into the receiving hopper, and finally into the bottom collection box. The probe continuously monitors the surrounding dust concentration. The dust collected in the probe hopper is filtered through an interface before entering the detection area. The detection sensor converts the concentration signal into an electrical signal, which is transmitted to the data module in the detection box. The data module processes the signal and displays the real-time concentration value on the touchscreen. When the concentration exceeds the alarm threshold, the device issues an audible and visual alarm. Residual dust generated during the detection process falls into the residual dust collection box for later analysis.
